I think the complete opposite will be true. People are so opinionated that film’s that would have had wider less passionate appeal will have smaller more passionate appeal. Thus creating more cult films, not less.

Reading Star Wars Wiki about Mara Jade made me think that there is a lot that can be done. At the end of the most recent trilogy the galaxy is essentially left at same spot it was at the end of the original trilogy. There is no reason why you can’t back story Jedi’s that got away into a new struggle to put the galaxy back together. The galaxy is essentially at the point where the USSR was when the wall fell.
